APS decided to take over hosting its own journals for a number of reasons. Most importantly, this change is part of a new initiative that aims to better integrate all services provided by APS to our readers, authors, referees, and members while providing a more personalized experience. The unified platform will also enable us to provide a comprehensive set of features across our entire online content from 1893 to present.

Circulation and fulfillment services for APS journals (invoicing, renewals, print fulfillment, online subscriber agreements) are still provided by AIP. However, APS has taken over maintaining IP ranges, usage statistics, institutional display names, and OpenURL services. APS has coordinated with AIP so that librarians will be able to keep using the same usernames and passwords to access services.

APS journal subscriptions have been re-aligned. Each journal subscription now covers the entire journal's content all the way back to its first volume. For example, a PROLA subscription is no longer needed to access the early volumes of PRL if you have a PRL subscription. However, a PROLA subscription is still needed to access Physical Review content from 1893-1969 and the archival content of journals for which you do not have a subscription. For APS-ALL and PR-ALL package subscribers, the main effect will be to attribute downloads of older content to the journal subscriptions rather than the PROLA subscription.

Librarians may now log in to https://librarians.aps.org/account and update their IP ranges, institutional display name, and their OpenURL server. IP range updates will be reviewed by APS staff before being becoming active. Subscribers who have access to AIP's Scitation Library Service Center may use the same username and password on the APS portal. To register, or for any other questions, please contact help@aps.org.

COUNTER-compliant reports are now available at http://counter.aps.org/. Subscribers who have access to AIP's Scitation Reports service may use the same username and password to access the APS Journals Usage Statistics site. To register, or for any other questions, please contact help@aps.org. Please note that the same username and password will be used on both the APS Librarian Portal and the APS Journals Usage Statistics site. Password changes may take up to 24 hours to propagate to the usage statistics site.
